Qiu Weixin checked the computer and said, "At the junction of Qinghai and Siyi, if the current downward trajectory is followed, the most suitable large airport is Shuangliu Airport!"
Bei Haiyang nodded. Shuangliu Airport is more suitable. It has good conditions in all aspects. It is backed by the big city of Chengdu and can meet any needs.
"It's just a double stay. Contact the ground and make an emergency landing according to the emergency requirements."
The current condition of DH-555 is not good. The obvious threat is that the No. 3 engine is penetrated and a piece of the roof is flattened. Furthermore, it is not known what collateral effects these two places will have. He is still
I don't know, I can only know when the plane enters the atmosphere and changes to civil aircraft mode.
There is also an unexpected burden. The big thing, which exceeds 50 tons, is lying on the roof of the DH-555. It adds a lot of weight in the air and has a considerable impact on the controllability of the aircraft.
It was uncomfortable to wait for the boots to hit the ground like this, and he didn't know what kind of bad situation he would eventually face. He seemed to be used to it.
At 25 kilometers, they started to ignite the engine. As the aircraft began to enter instrument flight, countless information poured in, and the true condition of DH-555 began to appear before their eyes.
"Engines No. 1, 2, and 4 ignited successfully, but the fuel consumption was a bit high. I suspect there is an oil leak near engine No. 3."
"Cut off the fuel balance, turn off the fuel master cylinder..."
Qiu Weixin was speechless, "You don't need to turn off the fuel master pump, it won't start at all!"
Looking at the page after page of error reporting interfaces on his computer, and listening to the endless beeping of the alarm above his head, Bei Haiyang sighed,
"How many error reporting options are there?"
Qiu Weixin quickly operated on the computer, page after page, "One hundred...well, 117 items! I guess I can't handle ten items before we run out of fuel!"
This is the collateral effect. Damaged circuits and hydraulic systems will cause numerous control obstacles. Bei Haiyang tried to control the rudder and found that the controllability of the aircraft had dropped to a very dangerous level.
"Weixin, please help me calculate the length of the runway required for landing."
Qiu Weixin immediately started operating on the onboard computer, and Bei Haiyang's voice came to his ears.
"Three engines are landing with full load, 50% rudder effect, 70% hydraulic pressure...use these conditions to calculate."
This is the landing calculation software for the 959 aircraft. It is used to calculate how long the runway is required for this large aircraft to stop.
"Computer analysis, we are dead!" Looking at the results, Qiu Weixin's face turned pale.
The key here is the extra tens of tons of weight; the 959 model can stop within 1,800 meters even when fully loaded, but this refers to the situation where the fuel consumption is about the same.
They are carrying a big dragonfly on their backs, just like they are carrying dozens of tons of fuel! The key is that they can't drain the fuel yet!
Landing with fuel is a taboo for aircraft landing, as there is a possibility of explosion and combustion. The most critical thing is whether the main landing gear can withstand such a huge impact; even if it can support it, the huge weight will make it difficult for the aircraft to brake, just like a
Heavy trucks and small cars have the same brake pads!
"The 3,500-meter runway at Shuangliu Airport is too short...but this is the longest among nearby airports. We don't have enough fuel to find another place!"
Qiu Weixin entered a total of nine failure factors before coming to the conclusion that they were dozens of tons heavier than the maximum required landing weight. This was the problem.
The heavier the aircraft, the greater the speed and runway length required for landing.
Qiu Weixin changed several parameters and calculated it again, but the result was still unsatisfactory.
Bei Haiyang gave a suggestion, "Maybe the big dragonfly is not as heavy as it looks? How much does it weigh?"
Qiu Weixin, "70 tons! It is slightly smaller than a human spaceship, which is generally around 90 tons..."
Bei Haiyang came up with a bad idea, "Maybe the inside of it is made of foam? Anyway, I don't think it is a steel product! Otherwise it can't be adsorbed on the top of the machine, even if it is 50 tons!"
Qiu Weixin felt that this was a bit self-deceiving, "Captain, it may indeed be a biological spacecraft, but because of this, it means that it is solid, not made of steel and has space inside...Okay, let's take it as 50 tons."
Qiu Weixin then entered some more optimistic figures, and this time the results were different.
"Well, it looks like the situation is pretty good. There should be 139 meters of runway left!"
A 3,500-meter runway can only have 139 meters of redundancy. This result is really hard to explain.
Bei Haiyang, "There is almost no room for error? Well, it's better than being over 139 meters! That's it!"
What speed should we approach at?"
Qiu Weixin looked at the computer and said, "The computer says it's section 146..."
Bei Haiyang said, "It's definitely not right! That's too slow."
Qiu Weixin was helpless, "You also know about computers..."
Bei Haiyang shook his head, "Don't worry about it! Let's approach the site at a low speed and keep it before the stall alarm sounds."
It is important to maintain the correct speed when landing. If it is too slow, the plane will lose lift and hit the ground. If it is too fast, the plane will run off the end of the runway and crash.
"If we add 20 knots to this speed, can we still stop on the runway?"
Qiu Weixin did some operations on the computer again, "166 knots? Wait... Okay, the computer said we will stop 5 meters from the end of the runway."
Bei Haiyang smiled bitterly, "Is this good news? Contact the ground!"
Qiu Weixin entered the channel, "Shuangli Tower, this is DH-555, the aircraft is seriously damaged, we need the longest runway, we also need fire trucks, ambulances, engineering vehicles, well, it's best to get a few more tanks...
…”
Shuangliu Airport, "Understood, clear ahead, runway 12 left, emergency preparedness, huh? You mean the tank? I didn't hear it clearly..."
Qiu Weixin repeated, "Yes, it's a tank, or any armored vehicle or something like that! There's also an extraterrestrial biological spacecraft lying on our plane, weighing more than 50 tons. You can figure it out. Anyway, if it wakes up, you have to be able to
Stop it!"
At Shuangliu Airport, the air traffic control stammered, "Wait a minute, we are not prepared for these things. I have to request support from the garrison!"
Bei Haiyang laughed and said, "You will scare them!"
Qiu Weixin shrugged, "We have been scared all the way, so we have to find someone to take over?
Captain, when you land, that dragonfly may be knocked down by that kick, so you must be prepared!"
Bei Haiyang nodded, fearing that this would happen. It would lighten the burden for them if this thing slid down in the air, but if it was rolled down after landing, whether it was to bring the wing or roll directly into
